Fix items membership with HTML like so:
```html
<div class="dd">
<ol class="dd-list" data-list-no="1">
<li class="dd-item" data-move-in="1">
<span>Parent1</span>
<ol class="dd-list" data-list-no="2">
<li class="dd-item" data-move-in="2"><span>Child1</span></li>
<li class="dd-item" data-move-in="2"><span>Child2</span></li>
</ol>
</li>
<li class="dd-item" data-move-in="1">
<span>Parent2</span>
<ol class="dd-list" data-list-no="2">
<li class="dd-item" data-move-in="2"><span>Child3</span></li>
<li class="dd-item" data-move-in="2"><span>Child4</span></li>
</ol>
</li>
</ol>
</div>
```
Items with `data-move-in="2"` can be dropped only in list with `data-list-no="2"`: "Child" Items can not be at the same level of their fathers
